This loop hike follows portions of the never-completed Dunderberg Spiral Railway, climbs to the summit of Bald Mountain, and passes several expansive viewpoints over the Hudson River.

From the parking area, walk south on Route 9W for a few hundred feet. Just beyond road signs for Routes 9W and 202, you'll see three blue blazes and three red-dot-on-white blazes on a tree adjacent to the road. These blazes mark the start of the Timp-Torne (blue) and Ramapo-Dunderberg (red-dot-on-white) trails. You'll be following the Timp-Torne...

Try the Hike in Reverse
I went up the RD this morning,as it is more exposed to the sun, and came back on the TT, which had more shade and less ups and downs.  I also extended the hike to the Timp, making a 10 mile loop. I started at 10:00, reached Bald Mt just after 11:00 and reached the Timp for lunch at 12:15. I was back at my car at 2:15 and drank about 2 quarts of water.  I didn't hike fast, but steady with almost no stops. I found the downs hard on my knees,even though I used trekking poles, but I am 62.  I had some breeze today and rain cooled things down overnight, otherwise I would start earlier in the summer.  Dunderberg had fires 20 years ago and the RD was much more exposed some years back, but the new growth provided shade most of the time.

nice hike, mind the snakes.
Wow was it hot today, but this hike was worth it! The path just challenging enough and the views were spectacular. I took the trail backwards, Ramapo-Dudenberg to 77 to Timp-Torne, and I noticed going up the Ramapo side first that finding red and white markers could be very challenging and I often had to backtrack to make sure I was still on trail. Also, there were a couple of larger fallen trees blocking the path between Dudenberg and Bald Mountain, forcing a new alternate path to be slowly formed in the high grass. I only point this out out of concern because as I was descending from Bald Mountain, I almost staggered upon a very large Timber Rattesnake that was hanging out right next to the  path in the leaves, high grass and brush. He was very kind to let me know that he was there with a vigourous shaking of his rattler and was also nice enough to forgive my foul language as he did take me by surprise.

Great Hike - Icy today, but still a fun hike
Good trail. One of the longer hikes that I have done - GPS logged it as 8.0 miles and I did it in 5hrs. & 20 mins. I followed the Red -on White Ramapo-Dunderberg blazes to the right after the trail splits. You will meet up with the Blue blaze Timp-Torne and follow them all the way home. The conditions were not ideal today - yesterdays rain left a frozen cover of ice on everything. The micro spikes saved my life today. The ice should melt in a day or two if the temps stay about freezing. Track is well maintained and marked. A few scrambles, but mostly nice walking in the woods. Will recommend to friends!
